We divide 161689 by 7
Our goal is to divide 161689 by 7.

On to step 1:
When dividing 1 by 7, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 7

Advancing to step 2:
7 goes into 16 2 times with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 14 from 16 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 7

Let's proceed to step 3:
21 divided by 7 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 23.0
If we subtract 21 from 21, we get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 7

On to step 4:
When dividing 6 by 7, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 230.0
If we take 0 away from 6, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 7

Going ahead to step 5:
7 goes into 68 9 times with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 2309.0
Subtracting 63 from 68 leaves us with 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 7

Advancing to step 6:
59 divided by 7 is 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 23098.0
Deduct 56 from 59 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 23098.4
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 23098.42
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 23098.428
Deduct 56 from 60 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 23098.4285
Subtract 35 from 40 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 23098.42857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 23098.428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 13:
7 goes into 30 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 23098.4285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 14:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 23098.42857142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 23098.42857142 with a remainder of 6e-09.
